I thought it was interesting how we talked about maths in different worlds. Like how a space shuttle would just blow up or drop dead once it “got into” a different universe. This was really weird to think about. I guess as somebody said, the logic behind the math is probably the same, just that the way people work it out may be different. The equational symbols or letters, words. However, the meaning behind it must all be similar. Or maybe everything is different, but when we move into a new universe, we also change to suit it’s surroundings.
